By surrendering electrons, the inner energy level that has eight electrons now becomes its
valence shell
Sodium atom with one valence electron
Sodium atom when it loses an electron
Notice that when the one electron is given away, it has the electron configuration of Neon
a Nobel gas.
The elements to the right of the diagonal line on the periodic table with the exception of
group 18 are non-metals. These elements are known as electron takers in ionic bonding.
